It’s been 100 years since the Spanish flu killed millions worldwide. While we’ve made medical and technological progress in the century since, the world remains vulnerable to mass disease.

Peter Piot, Director of Global Health at the London School of Hygiene & Tropical Medicine, talks with Markos Kounalakis, visiting fellow at Stanford's Hoover Institution, about the importance of effective outbreak preparedness.
